Vivoactive 3 Strap Keeper

I wanted one that was more tight that the ones I've found here. You have to vend the watchband a little to fit it in, but works nice, like, it won't come out on it's own. The Fusion 360 file is up too, so you can make any change you need/like. And if it helps you, and you make it, please post it! Thanks!
